Boiler type Heat loss per heat input of fuel Oil fired boiler 0,2 - 0,5 % Coal fired boiler, dry ash removal 3% Coal fired boiler, molten ash removal about 2 To decrease flue gas losses, flue gas exit temperature should be decreased.
suijitupian91.jpg" />The examples of the fire tube boiler are: simple vertical boiler, Cochran boiler, Lancashire boiler, Cornish boiler, Locomotive boiler, Scotch marine boiler and Velcon boiler. (ii). Water Tube Boiler: In water tube boilers, the water is present inside the tubes and the fire or hot gases surrounds these water tubes.
suijitupian94.jpg" />Precautions to be carried out at Start in Steam Boilers: Hydraulic should be carried out at a defined pressure before the start of a boiler. Check if the pump inlets are open at the start of a boiler. Install an automatic ash removal system such as rotary valves in a boiler so as to prevent the accumulation of ash in a furnace or other equipment.

suijitupian53.jpg" />The primary boiler fuels are coal, oil, and gas. Oil and gas involve the simplest controls, since they can be measured easily and flow is regulated by a control valve in the fuel line. On the other hand, since coal is an unmeasured fuel, the control system is open-loop, in which a fuel demand signal positions a coal-feeding device (speed
